specification farming part ofLetters Patent No. 42,071, dated March 29,Y 181:4.

-Beit known that I, E. W. BULLINGER, of

invented anew and Improved Gas Heating exact description of the same, reference being had -to the accompanying drawings, forming part of this specification, in which- Figurel represents a vplan or top view of my burner. Fig. 2 is a vertical, central seccration. Fig. 3 is a modicationof the saine. Fig. 4 is a plan or top view of the socket and platform which supports the burner.

Similar letters in the several views refer to corresponding parts. l

The object of this invention is to\ produce the largest possible heat by the consumption of the least possible quantity of gas.

To enablethose skilled in the art to make and use my invcntioin'l will proceed' to de# A represents a cylinder or inverted truncated cone, open at both ends and inclosing one or more cylinders, B, which are also -open at both ends, and which are so proportioned in relation to the outer'cylinder that an annular chamber, C, is formed in which the gas mixes with atmospheric air. The top end of der and projecting edge,or .ther`e may be over. the top of it a cap, D, fitting overa shoulder, a, This cap has a projecting edge, b, `either straight, oblique, or curved upward, as may be desired. The inner cylinder, B, mayk be of the vsanne length as the outer one and cap combined, so as to bring its upper edge on a level with the upper edge of the cap, or it may be somewhat longer or shorter, as may be found advantageons, or it may be of the same length as the outer cylinder, and have fitted over the top of it a cap, E, of any height,with an edge, o, either straight, oblique, or curved.

Between the two cylinders is placed a piece of perforated metal, I, held in place by its y/ voutside edge or. circumference beiugcla-mped between thecap D and upper edge or shoulder,

a, ofthe outer cylinder, audit' found neces? sary by similar means on the inner cylinder.

This perforated metal disk acts as a stay or brace to hold the` two cylinders in position and also prevents .the fia-me from falling belowy and igniting the gas in the mixing-chamber,

or at-th'e perforations in the gas tubeor coi` ductor. y l

l The cylinder may beheld steady below by His the pipe which conducts the gas to the burner, and this pipe is provided withtwo oblique perforations,f, which throwthe gas -in an upward inclined direction into thechamber O. --This chamberbeing open at the bottom admits a current of atmosphericair, which freely mixes with the gas,the operation Aof lpassage or passages, B,and, if the gas has sufficient pressure, the darne forms an annular cone, as shown iu Figs. 2` and 3, and not a particle'of gas is allowed to escape without comingin contact with a sufiicient'quantityof at mospheric air to consume it. By these means a great economy in gas is effected and an ap-v paratus is obtained which can be' used with considerable advantage for heating or cooking purposes.

What I claim as new, and desire to secure by Letters Patent, is- The combination of the edges b c with .an

annular gasmaking chamber, G, and its diskf F, substantially as herein shown and'described.
